Yamaguchi Motorcycle 1963

I have a Yamaguchi motorcycle, looks like the one pictured (not actual bike pictured) but in non running, sat for a while condition. No seat cover on mine. Anyone know where to get parts for this thing? Looking for any info you may have on this bike. I know that they are the predecessor to Hodaka, but that's all I know. May also sell or trade for old scooters/parts, etc. I'm in WY.
